最近有一个关于H-1B 第七年延期的问题，我们认为有必要提出來说明：
Q: I am in my 7th year H1B with company B. My labor was filed in Delaware with
company A. I got my 7th year extension using Company A's pending labor. I am
planning to join company C to do the labor substitution to use their
preapproved labor. My 7th year H1B will expire on Aug 2005. 1) If I do labor
substitution with Company C, Can I get 8th year extension based on the
approved labor of Company C?
首先我想说明法律的相关规定。H-1B的身分原则上有六年的限制，而在AC21法案做了修正
之後，其中一项新的规定是让H-1B身分
